Final answer:
When you travel west in Texas, the elevation increases and precipitation decreases due to the rain shadow effect.
Step-by-step explanation:
When you travel west in Texas, the elevation increases and precipitation decreases.
The western United States, including Texas, experiences a rain shadow effect. As the air rises over the mountains, water vapor condenses and returns to the earth as rain or snow. This means that west of the mountain ranges in Texas, there is much less precipitation than to their east, resulting in arid and semi-arid lands.
For example, in the shaded relief map of Texas, the red and white colors represent high elevations, while the greens and yellows represent lower elevations. Areas with higher elevations are found in the western part of Texas.
